“…S INGLE-PHASE permanent magnet (SPPM) synchronous motor with a U-core stator has been widely used in many low-power household appliances and industrial tools, because of its simple design, low cost production and higher efficiency than rival motors [1]. However, PM machines have a cogging torque and a torque ripple issue, resulting in vibrations and noise [2].…”

A Novel Two-Phase Permanent Magnet Synchronous Motor Modeling for Torque Ripple Minimization

2013

This paper proposes a novel two-phase, two-pole, permanent magnet synchronous motor (PMSM) with dual U-core stator structure for torque ripple minimization. The proposed motor is modeled based on the conventional single-phase U-core PMSM with approximate output power and core dimension. Torque ripple in the novel motor can be reduced significantly due to 90 electrical angle phase shift in two sets of magnet pairs and 90 shift in two-phase excitation currents. Characteristics of both PMSMs such as back-EMF, cogging torque and electromagnetic torque are analyzed and compared by using the 3-D finite element analysis (FEA). As shown in the result, the cogging torque and torque ripple in the novel two-phase PMSM are efficiently reduced with sinusoidal back-EMF waveform and reasonable current density value. The validity of both PMSM models is also verified by the comparison between simulated and experimental measured results.Index Terms-Cogging torque, dual ferrite pole pairs with 90 electrical angle shift, electromagnetic torque, FEA, torque ripple.

“…The main motor advantages are simple design, low cost production, as well as higher efficiency than rival motors. However, on the other hand, these favourable properties of the single-phase permanent magnet motor stand opposite to the restrictions concerning their self-starting ability and stability (Ertan, Dag & Capolino, 2005).…”

The International Symposium on Applied Electromagnetics is aimed at the presentation of research work results in various areas of Applied Electromagnetics. The Symposium is devoted to exchanging ideas, presenting achievements and results, providing the forum for researchers and academics. Open and friendly atmosphere, which our conferences are known for, encourages especially young researchers to present their achievements and ideas, even at an early stage of their research work. The Symposium continues the tradition of joint conferences, organised in previous years by the organisers from Macedonia, Poland, Slovenia and Hungary. The symposium is open for participants from all over the world. This year's symposium took place between 17th and 20th June 2018 in Podčetrtek, Slovenia. We would like to thank all the participants for their participation at the International Symposium on Applied Electromagnetics and wish them a successful academic career.

“…Single phase interior permanent magnet (IPM) motors are adopted in many low cost applications such as in fan, blowers, and other domestic appliances [1][2][3][4][5]. The main disadvantage of using single phase compared to three-phase permanent magnet motor is its inability to self-start [6][7][8]. However, for specific application such as the mechanical chopper, the single phase motor is the most popular application due to the safety consideration.…”

The paper presents the energy density improvement using magnetic circuit analysis of the interior permanent magnet motor. The leakage flux from the conventional structure is improved with modified magnetic circuit to improve the energy and thereby the torque value. This is approached with a double stator structure design. The proposed structure is investigated with two design variations, namely, the double stator with thin pole shoe and the double stator with thick pole shoe motors. Variations in the mechanical parameters of the all the developed models are analyzed through the finite element analysis tool. In all investigations the magnetic source is fixed in both the permanent magnet volume and coil magnetomotive force, respectively, as 400 mm 3 per each pole and 480 Ampere turns per pole. From the analysis the best fit magnetic structure based on the torque characteristics is derived and is fabricated for the same volume as that of the conventional structure for performance evaluations. It is found out that there is improvement on the motor constant square density for the proposed improved magnetic circuit through the best fit double stator with thick pole shoe by about 83.66% greater than that of the conventional structure.
